Did Melissa Tancredi Stomp On Carli Lloyd's Head?

The Canada versus United States semi-final Olympic match was a testy affair, what with the two rivals battling to see who would play Japan in the final for the gold medal. But it looks like Canada's Melisssa Tancredi took the competitive battle a bit too far and stomped on Carli Lloyd's head after she fell down.

I wonder if this is what Canada's coach John Herdman was referring to when he said the United States team used some "illegal tactics" and are "very good at it". He might want to have a look at his own team. Take a look.
